Emergency medical services (EMS) are supervised by the Deputy Chief of EMS along with the support of the Battalion Chiefs. Those assigned to emergency medical services are firefighters, but in addition, they are state certified paramedics and can provide advanced cardiac life support (ACLS).

Designated emergency medical personnel and equipment are placed at all five fire stations, and they respond to approximately 8,400 ambulance requests each year. The City of Janesville also contracts with surrounding townships so that the total area covered is approximately 108 square miles.

Emergency medical personnel also work with suppression personnel to routinely inspect local businesses and apartment buildings for fire hazards and safety violations.

In addition to certified paramedics, the emergency medical service also includes individuals trained as EMT's and in basic life support skills (BLS). These Firefighters can respond to medical emergencies when the Paramedics are already committed or if they arrive first at the scene. The Fire Department provides five ambulances staffed by Paramedics. 

Emergency medical personnel respond to requests for emergency medical aid, fire calls, rescue calls, or whenever their special skills are needed.
